BASIN-WASTE CONNECTION.

To all whom it may concern:

Be it known that we, FRED HOFFMANN and EDWARD F. NIEDEOKEN, residing in Milwaukee, in the county of Milwaukee and State of Visconsin, have invented new and useful Improvements in Basin-Taste Connections, of which the following is a description, reference being had to the accompanying drawn ings, which are a part of this specification.

This invention has for its object to provide a connection for a basin waste or the like which is adapted to it upon an inclined surface with a neat lit leaving no gaps or openings and at the same time have the waste pipe in a perfectly vertical position.

In modern lavatories of vit-reous china the surface of the slab is usuallyV inclined inwardly from all sides to drain into the bowl and consequently it has been diiiicult to fit the waste and other pipes projecting through the slab to the inclined surface without throwing the pipe out of its proper vertical position. With this invention the desired result is accomplished by providing a sleeve to fit upon the inclined surface of the slab and having a flange and socket connection, in the nature of a ball and socket joint, with the pipe or part projecting through the slab to form a close fitting with-. out gaps or `openings and presenting a neat and ornamental appearance.

With the above and other objects in view the invention consists in the basin waste connection herein claimed, and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in the different views; Figure 1 is a sectional rear elevation of a basin waste connection constructed in accordance with this invention; Fig. 2 is a side elevation thereof with the basin in section; Fig. 3 is a plan view thereof; Fig. 4 is a front elevation of a modified form of the invention; and, Fig. 5 is a bottom view of such modication with the pipes in section.

In these drawings 10 indicates a basin having a surrounding slab 11 which is inclined so as to drain from all sides into the basin. A drain pipe 12 leads from the bottom of the basin and has a slip joint union connection 13 with a drain T 14 forming a valve seat 15 at its lower end where it is connected with the waste pipe 16 and having a slip joint union connection 17 at its upper Specification of Letters Patent.

end with the standard tube 18 of the waste. The standard 18 passes through an opening in the slab of the basin and the present invention resides in the means for fastening the upper end of the standard 18 to the inclined slab of the basin so that the parts will neatly fit thereon. A nut 19 is threaded on the standard 18 and engages a clamping member 20 which is provided with opposite upstanding lugs 21 to engage the under side of the basin slab, while a collar 22 is threaded on the upper end of the standard and has a beaded shoulder engaging a socketed conical sleeve 23 which rests flat upon the upper surface of the basin slab. The sleeve has its upper edge recessed to form the socket for neatly fitting the rounded shoulder of the collar 22 in yany of its angular Yadjustments thereon permitted by its flaring lower end. The usual strainer tube.

24 is located within the standard 18 with free space between them and carries a tapering valve plug 25 at its lower end to fit on the valve seat 15. The strainer tube also has a fianged head 26 at its upper endl to normally rest on the collar 22 with a stud 27 projecting therefrom to engage an internal cam flange 28 of the collar 22 for lifting the strainer tube 24 when the head 26 is turned and thereby remove the valve 25 from its seat.

This waste pipe connection with the slab of the bowl assures a neat fit of the parts without gaps or openings because of the ability of the sleeve 24 to stand at various angles in any direction with. relation to the collar 22 and furthermore because of the diametrically opposite bearing points for the clamp on the under side of the basin slab which afford a firm clamping engagement with the slab notwithstanding the incline thereof and the vertical position of the waste pipe.

By means of this invention it is not necessary to incline the waste pipe -in order to make a neat fit with an inclined slab and the appearance of the fittings is not detracted from by reason of their adjustability.

The modification shown in Figs. 4 and 5 is for a combination waste and supply, and only differs from the construction shown in Figs. 1, 2 and 3 by having the casing 24, corresponding with the sleeve 24, adapted for connection with the hot and cold water supply pipes 29 Which communicate through the interior thereof with the faucet 30, and furthermore the member 20, corresponding with the member 20, is made sufficiently large to surround the supply pipes '29 and has the lugs 21 at its ends dametrically opposite each other as before t0 form the clamping engagement with the under side of the slab. The advantages referred to in connection with the form of the invention shown in Figs. l, 2 and 3 apply also to the modification thereof shown in Figs. 4 and `5.

It is evident that the exact details of construction herein shown and described may be varied Without departing from the spirit and scope of the invention.

What We claim as new and desire to secure by Letters Patent isl. A pipe connection for basins and the like, comprising a clamping member mounted on the pipe and having diametrically opposite upstanding lugs to form a clamping engagement With the under side of the basin slab, a shouldered collar secured to the pipe, and a sleeve surrounding the collar and having an angularly adjustable bearing thereon to permit it to lie flat upon the inclined upper surface of the basin slab.

2. A pipe connection for basins and the like, comprising a clamping member mounted on the pipe and having a pair of diametrically opposite upstanding lugs to engage the bottom surface of the basin slab, a nut threaded on the pipe and supporting tne clamping member, a' collar having a rounded shoulder, and a sleeve provided with a socket at its upper end to lit the rounded shoulderof the collar and permit of the sleeve being angularly adjustable With relation to the collar Without interfering With the lit of the socket and shoulder, said sleeve being thereby adapted to fit the inclined upper surface of the basin slab, and the nut serving to clamp the several parts together in their adjustments. s

In testimony whereof, We affix our signatures, in presence of two Witnesses.
